Does my computer have good airflow? *UPDATED PICS*

So My question is, is my airflow good for 24hr use if turned into a server?

The only fan that was in this computer was the exhaust fan with an air duct channeling cool air through the cpu heatsink. I've added a new INTAKE fan, aswell as a very small Northbridge fan because it can burn you're skin after watching a movie on the computer.
I connected the two extra fans via the 12 volt leads on 2 extra molex connectors (Highlighted in Green). Cold air is sucked through the front of the case passing through the two Harddrives seated vertical.

UPDATE:
The amount of dust... just makes me speechless. Put the fan in the front, zip-tied it down, and soldered on a blue "power" led to replace the tacky green one. I guess the dust was the reason why I didnt feel any air coming out of the back.

Good enough but keep in mind about when or if you ever do decide to get a new agp card that you wont have the best temps.

Not bad but not the best. I recently did a fan mod my self. I used a 15 year old 20mm fan to cool my NB.

20mm? I bet you mean 40mm....

Good job on dusting and the fan. Is the green shroud staying on or off? Might want to test it both ways and see what helps. Hate to burst your bubble, but I doubt that front fan will do much good. Not with those drives in the way.

I think mine is a 40mm aswell, (the NB fan I installed)

The green duct has to stay on as it lets the exhaust fan suck all of the cool air directly through the CPU heatsink.

To be honest, If I put my hand near the top of the HDD theres plenty of air being pushed through, its a lot better than all of that dust in the way thats for sure!

Also It cools the HDDs down, as they get kinda hot.

When I get a chance Im going to attempt to put the HDDs horizontally so that even more air can get in! Im curious to see what the panty hose will look like in 20 days.

BTW with the green duct off, not much air passes through the heatsink and it gets hot.

Is the rear fan blowing in or out? I'm guessing is blowing out, and with the duct on it picks up more of the heat from the CPU. The question then becomes what is the relation between the system and CPU temp with the cover on and off.

oh you meant the cover? Well to be honest there is no way of me being able to monitor the temps exept for touching the heatsinks with my bare hands as the Pentium 4 doesn't support ANY temp monitoring program and the bios doesnt have it either. The rear fan blows air out sucking air through the duct.

Kinda hard for me to tell. The only 40mm fan I have laying around right now uses clips and not screw holes so its a bit wider. With the quarter on the corner like that its hard to tell how much of side it takes up. 40mm fans are the smallest I've seen, I'd be surprised if there was a 20mm.
